READ-CHAR-NO-HANG misbehaviour on Windows Console

[Nikodemus Siivola]

BUGS #421

It seems that on Windows READ-CHAR-NO-HANG hangs if the user
has pressed a key, but not yet enter (ie. SYSREAD-MAY-BLOCK-P
seems to lie if the OS is buffering input for us on Console.)

This bug hinders SLIME from working correctly with SBCL on Windows.

See http://article.gmane.org/gmane.lisp.slime.devel/7991 for more details.

I hence propose to change the Importance of this bug to High.

[Nikodemus Siivola (nikodemus)]

Marked as HIGH, but this is for now best worked around in Slime.

(Intrepid Windows people: the place look at is src/code/win32.lisp, DEFUN HANDLE-LISTEN.)

[Alastair Bridgewater (alastair-bridgewater)]

Knocking this down to Medium because SLIME has had a workaround for quite a while, and there has been no activity on this in more than a year.
